The TEM module is not very comprehensive but for a first semester course it is probably sufficient. If you want a good resource for TEM I recommend the book Transmission Electron Microscopy by David B. Willliams and C. Barry Carter. I got this as a four volume paperback set. It looks like it is now in a hardcover version available from Amazon at the following web site:
One of the best nanoscience resources is Nanohub. Nanohub has a variety of different resources available but one of the most abundant is the set of online presentations which can be accessed from the following web site:
The presentation I want to refer to here is:
"Electron and Ion Microscopies as Characterization Tools for Nanoscience and Nanotechnology"
This is a good presentation on electron and ion microscopy techniques but the part I found particularly fascinating was the section at the end where they show carbon nanotubes growing inside an environmental TEM.
The activity I do for this section is based on the web site:
This site has some excellent Java based simulations. Besides TEM they also include a number of other modules going up to the top level.
Although we do not have a TEM here at CVTC our partner institution University of Wisconsin Eau Claire has a nice 200 keV system and this week we went on a field trip to the UW Eau Claire Materials Science Center which has a good collection of analysis equipment.
